Review on Dayton Audio HTA20BT Hybrid Stereo Tube Amplifier: Bluetooth 4.2, USB Aux in, Headphone & Sub Out by Carolyn Brown

I decided to replace the BT speaker I was using in a very large bedroom and bought this. I added a pair of Bic bookshelf speakers that I once used as the rear channel in a surround sound system and a Polk subwoofer that I didn't use. I received the comments in the posts and spent a few minutes playing around with the equalizer in Spotify. Aaaaaaaaaaaaaaaaaaaaaaaaa. Much better than I had hoped. Huge sound stage. Really warm, rich overtones. I'm doing something I haven't done in a long time, which is sitting and listening to music. Even melodic tracks sound good. More than enough punch to fill a room with dance party volume when needed. I can't believe it was worth just what it did. If you can't say I'm very happy with this purchase
